In the year 1840, he opened a little shop in Upper King Street, Bloomsbury, and he carried on precisely the same trade as his father did in Cheyne Walk. By degrees, however, he neglected the newspaper and general stationery business, and devoted himself more exclusively to the circulating library, which he increased at such a rapid rate that the father became alarmed at the speculative spirit of his son. In 1842, Mr. Mudie commenced his system of lending out one exchangeable volume to subscribers at the rate of a guinea per annum; and as he made the addition of every new work, immediately upon its publication, a feature in his establishment, he produced an entire revolution in the circulating library movement, and was rewarded by a rapidly increasing number of subscribers. Nor did he at this early period confine his dealings solely to circulating the books of other publishers. He was himself in some instances a publisher, and from his establishment issued the first English edition of James R. Lowell’s “Poems,” and Mr. George Dawson’s first “Orations.” In 1852 the library had grown too large for the house in Upper King Street, and he removed his business to two houses which form part of his present establishment--the penultimate house in New Oxford Street, and the penultimate house in Museum Street; and though the corner house intervened, the two were connected by a passage. Gradually, as the business grew, the houses on either side were absorbed. In 1860 the large hall was opened, and inaugurated by a festive gathering of literary men and publishers; and the entire block of building, as it stands at present, occupies the sites of eight houses, and even now great additions are being made to the rear of the premises. As the popularity of the library increased, branch houses were opened in the city, in Birmingham and Manchester, and arrangements were made with literary institutions, provincial libraries, book-clubs, and societies. The magnitude of the business had, however, now grown beyond the limit of individual capital, and, in 1864, Mr. Mudie found it desirable to form his library into a limited liability company. The value of the property was estimated at £100,000; of this he reserved £50,000, and the remaining £50,000 was immediately subscribed by Mr. Murray, Mr. Bentley, and other publishers; Mr. Mudie’s services being, naturally, retained at a salary of £1,000 per annum, in addition to his half interest in the business. This change, and the increase of capital, proved in every way beneficial to the expansion of the library; and since penning this account we have received a circular announcing an enormous increase of business. From the 18th August, 1871, the Directors of Mudie’s Select Library (Limited) became possessors of the English and Foreign Library and its large connection. This library, which was originally known as “Hookham’s,” at one time possessed one of the finest collections of rare and valuable standard works in London.
